Cranial nerve XII (name & function)

A

XII = hypoglossal = tongue movement

think = lick your lips (tongue) to make them glossy.

139
Q

What is the BP equation

A

BP = CO x SVR

140
Q

What’s the equation for cardiac output

A

CO = SV x HR

141
Q

What’s the equation for MAP?

A

MAP = DBP + 1/3 (SBP -DBP)

142
Q

What’s the formula for Stroke Volume

A

SV = preload x contractility mediated by afterload (AKA SVR)

143
Q

What is the pediatric BP formula

A

SBP = 70 + ( 2 x age)

144

A

Tissue identical to endometrium grows outside uterus = ectopic pregnancy risk

148
Q

What organ controls your breathing? How?

A

Po2, Pco2, pH

155
Q
